Application January 17, 1947, Serial No. 722,546 6 Claims; (Cle. 12S-40d,

This.e invention relates.v to brick cutting tools.

It' isanobject.v of the present: invention: toi pravide a. brickl cutting! tool. with: a measuring device thereon adapted to be rested. over theatop of.x the brick and' te actautomatically asi an engaging element i'sf made to: engage v to: thev end of' theibrick, to measure oi the desired amount of brick. which is tobecutfrom the iull brick..

It is another object of the: present inventihn toprovide a measuring device for a` brick. cutting tool whichI can be readily treed: once. the meas'.- urement has been made so.v that thevcutting; tool can be raised atanangle without' interference@ to eiect an undercutting ot the brick.: Whenutlf-re severance of the same* i'sveiecte'dl It is. stilll another object; of the present'. ini/.enft'ion toA simplify the procedurel of effecting the measurements upon'` the brick' whereby theworkiman canwithout separate-L operationshaving;l to first measure off' a distancev on a brick andi mark the same, apply the device readily Withonehand while retain-ing' a striking hammer in theA4 other hand' and whereby to= reduce the. num-ber of operations incutting a brick and whereinthe cutt'ifng of the' brick can be done with: safety.

For other objects andi for' a: better understand*- ing of the invention, reference mayfbe had to the following detailed description. taken in connection with the accompanying drawing, inl .w-liichl Fig. I is# a side elevationall view ofthe cutting and measuring' tool? disposed irl-placeupon a; brick in preparation for the cutting of the brick,v tiie or the like',

Fig. 2 is a similar side elevational view with rthe cutting tool? having been til-tedL andthe Ineas;-

uring portionL having been raised therefrom: in preparation for the effecting of' a striking operaition upon the' cutting' tool,

Fig. 3 is a fragmentary top plan view of the measuring stick portion and` of' the slide thereon,

Fig; Ik is a, fragmentary View of the slide with its top portion broken away to.-

the hinged engaging plate on its. bottom sideI which carries the engaging element' which contacts the end of the brick.

Referring now to the. figures,V Ill represents a building brick adapted` to. befcut. When. this. operation is: to; be. effected.. acutting chisel. orl tool II having a sharp cutting edge I2 is placed on the top dof the brick. Thereafter the chisel is struck and the end of the brick is knocked 01T. Inasmuch as it is desirable to have the piece to be put into the wall to have an undercut end, the chisel is tilted as shown in Fig. 2 and retained in this position as the cut is made.

i' sama is; usen*` with little more. effort than applying* the; einser directly to:I theV brick. k(imeifereion thecchisell lili: is groomed as indicated at I3 to receive an upturned portion I4 of a measuring member I5. This upturned portion I4 Will engager with the: sides of; the groove' and prevent .any lateraliv displacement of the measuring memben 'L5 relatwertov thea chisel.. 'lihis portion I4 is securedwithim thefgnooye: and; to the chisel bythe disposai ofi a. screw' I6 through a slot I'I in the attenuation: wenn intoiatn-readeehoie is on the cutting; tool Ik.

'itl-1e.opposite.` edges of the measuring member are provided .wlthindentations t9 and 2i). These indentations are preferably staggered: as between `the opposite sides of the member. This is so that ai more accurate: measurement can be effected.

severing the same.

tacting element 29 will engage the end of the brick as shown in Fig. 1. This is done after the adjustment of the slide has been made upon the measuring portion l to the proper length of cut to be eiected upon the brick. Thereafter, the chisel is tilted, Without the contacting element catching and without it leaving brick end face, to the position shown in Fig. 2 and is permitted to do so by virtue of the fact that; the contacting element 29 is carried upon a hingeable plate 28. The workman will be able to do this without the contact element 29 rendering any interference to the movement of the chisel. Thereafter the chisel is struck and the brick is severed. The plate 28 is of suiiicient Width that there is little opportunity for the chisel to be shifted laterally to any great extent. f

It should now be apparent that there has been eliminated several of the usual steps which have heretofore been necessary in the cutting of a brick to the proper size. vThesteps'which have been eliminated are the measuring, marking and It is no longer necessary to get down on the knees on a scaioldto. measure and mark the brick. A more accurate'cutting of .the brick is eiected whereby to save time and material. The brick which has been cut with this tool makes a more true bond. .n

While various changes may be-made inthe detail construction it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

I claim:

1. A cutting tool for brick, tile and the like having a cutting edge and a portionadapted to be struck with a hammer, a measuring" member xed to one face of the tool and extending rearwardly therefrom, a slide adapted to be adjusted along the measuring memberto diierent distances from the cutting edge of the tool, andan engaging element disposedon the slide adapted to iit over the end of the brick and -engage with the end face thereof. y f

2. A cutting tool for brick, tile and the like having a cutting edge and a portion 'adapted to be struck with a hammer, a measuring member iixed to one face of the tool and extending rearwardly therefrom, a slide adapted to be adjusted along the measuring member to different distances from the cutting edge of the tool, and an engaging element disposed on` the slide adapted to iit over the end of the brick and engage with the end face thereof, and meansfor hingedly connecting the engaging element to the slide so that the measuring member and the Slide may be raised or tilted freely and Without disengaging the engaging element from its point of contact with the end of the brick and whereby to permit the cutting tool to have the propertilt so as to 'effect an undercutting of thebrick' piece when 3. A cutting tool for br1ck;ti1e and the like having a cutting edge and a portion adapted`to 'be struck with a hammer, a measuring member xed to one face of the tool and extending rearwardly therefrom, a slide adapted to be adjusted along the measuring member to dilerent distances from the cutting edge of the' tool, andan Wardly therefrom, a slide adapted to be adjusted along the measuring member to diierent distances from the cutting edge of the tool, and an engaging element disposed on the slide adapted 1to fit over the end of the brick and engage with the Vend face thereof, and means for hingedly connecting the engaging element to the slide so that the measuring member and the slide may be raised or tilted freely and without disengagingthe engaging element from its point of contact with the end of the brick and whereby to permit the cutting tool to have the proper tilt so as to effect an undercutting of the brick piece when severing the same, and a spring associated Awith the hinge connection of the means whereby to normally maintain the plate with the engaging element in a raised position and against the bottom of the slide.

5. A cutting tool for brick, tile and the like having a cutting edge and a portion adapted to be struck with a hammer, a measuring member xed to one face of the tool and extending rearwardly therefrom, a slide adapted to be adjusted along the measuring member to diierent distances from the cutting edge of the tool, and an engaging element disposed on the slide adapted to fit over the end of the brick and engage with Athe end face thereof, said measuring member tances from the cutting edge of the tool, and an engaging element disposed on the slide adapted to fit over the end of the brick and engage with the end face thereof, said measuring member -having notches upon the opposite edges of the same, and catch elements on the slide in its -adjusted position, and said notches on the opposite edges of the measuring member being respectively staggered with one another so that a closer measurement can be effected.
